A Novel Porous Diamond - Titanium Biomaterial: Structure, Microstructure, Physico-Mechanical Properties and Biocompatibility.
With the aim of introducing permanent prostheses with main properties equivalent to cortical human bone, Ti-diamond composites were processed through powder metallurgy. Grade 1 titanium and mixtures of Ti powder with 2%, 5% and 10 wt% diamond were compacted at 100MPa, and then sintered at 1250°C/2hr/10-6mbar. Sintered samples were studied in the point of view of their microstructures, structure...
متن کاملMicrostructure and Mechanical Properties of Reticulated Titanium Scrolls
Titanium and its alloys find widespread use in skeletal implants and biomedical devices (e.g., stents and orthodontic applications) owing to their excellent corrosion resistance, bio-compatibility, static and fatigue strength, and lack of magnetism (an important property for magnetic imaging). Microporous titanium provides two additional advantages for implant applications: first, it reduces th...
متن کاملBiocompatibility and mechanical properties of diamond-like coatings on cobalt-chromium-molybdenum steel and titanium-aluminum-vanadium biomedical alloys.
Diamond-like carbon (DLC) films are favored for wear components because of diamond-like hardness, low friction, low wear, and high corrosion resistance (Schultz et al., Mat-wiss u Werkstofftech 2004;35:924-928; Lappalainen et al., J Biomed Mater Res B Appl Biomater 2003;66B:410-413; Tiainen, Diam Relat Mater 2001;10:153-160). Several studies have demonstrated their inertness, nontoxicity, and t...
متن کاملMicrostructure, in Vitro Corrosion and Mechanical Properties of porous Magnesium-Zinc Nanocomposite Scaffolds
Due to good biocompatibility, corrosion and mechanical properties, magnesium (Mg) is considered promising degradable material for orthopedic applications. In this work, Mg-MgZnx (x= 1, 2, 3 and 4) nanocomposites scaffolds with different porosities were synthesized via powder metallurgy method. The microstructure, composition, in vitro corrosion and mechanical properties of porous magnesium-zinc...
متن کاملBiocompatibility and osteogenic properties of porous tantalum
Porous tantalum has been reported to be a promising material for use in bone tissue engineering. In the present study, the biocompatibility and osteogenic properties of porous tantalum were studied in vitro and in vivo. The morphology of porous tantalum was observed using scanning electron microscopy (SEM). Osteoblasts were cultured with porous tantalum, and cell morphology, adhesion and prolif...
